Where Does the Duty Come From?

Although the obligation is spelt out in the Federal Circuit and Family Court of Australia (Family Law) Rules 2021, the Family Law Act 1975 (Cth) shows how disclosure underpins fair decisions:

• Section 79 requires the Court to alter property interests only if it is just and equitable - something it cannot do without reliable figures.
• Section 75(2) lists the financial factors that must be considered when fixing spousal maintenance; again, honest disclosure is vital.
• Section 79A(1)(a) allows the Court to set aside a property order if there has been a miscarriage of justice caused by suppression of evidence or giving false evidence.
• Section 90K(1)(a) & (e) empowers the Court to invalidate a binding financial agreement if a party failed to disclose material matters or engaged in fraudulent conduct.
• Section 117 lets the Court order a defaulting party to pay the other side’s legal costs. Non-disclosure is a classic reason for an indemnity costs order.

Together, these provisions confirm that disclosure is not voluntary etiquette, it is a statutory imperative.

What Must I Disclose?

You must provide every document or piece of information that shows:

• Current assets and liabilities – property valuations, mortgage statements, bank and credit-card statements, shareholdings, cryptocurrency wallets, motor vehicles, superannuation balances.
• Income and resources  – payslips, tax returns, trust distributions, bonuses, fringe benefits, rental income, options or pending inheritances.
• Financial dealings over the past three years – asset transfers, gifts, loans to family companies, redraws on lines of credit.
• Business interests – partnership agreements, company constitutions, BAS statements, management accounts and depreciation schedules.

A helpful rule of thumb: if the document alters or evidences your financial position, disclose it.

When and How do I Disclose?

1. Early – disclosure should begin before any court application, continue through negotiations and be updated whenever circumstances change.
2. In writing – supply clear copies (scanned pdfs are fine) and keep a list of what you have handed over.
3. Formally if required – once proceedings start you will need to file a Financial Statement under the Court Rules.

Timely and organised disclosure not only complies with the law but also narrows the issues and reduces costs.

What Happens if I do not Comply?

Failing to disclose, or worse deliberately hiding the truth, can backfire dramatically:

• Adverse inferences – the Court may assume the undisclosed asset exists and award a larger share to the innocent party.
• Set-aside orders – even years later, a property settlement or financial agreement can be overturned under s 79A or s 90K, reopening the entire dispute.
• Cost penalties – s 117 allows the Court to make you pay the other side’s solicitor-client costs, wiping out any tactical gain.
• Contempt or criminal action – swearing a false affidavit is perjury; hiding assets to defeat a claim may amount to fraud.

In short, non-disclosure is a high-risk strategy with no upside.
